Evidence that interspecies Leishmania hybrids contribute to changes in disease pathology

Abstract: AbstractBackgroundLeishmaniasis is a widespread neglected tropical disease present in over 90 countries with diverse pathologies associated with different species of Leishmania parasites transmitted by infected sand flies. Leishmania donovani causes visceral leishmaniasis, a highly virulent fatal infection of the visceral organs. Leishmania major and Show more

“…PCR-free library preparation (Lucigen) and NextSeq 500 sequencing (Illumina) was performed at Genome Quebec. Raw reads were processed as described 72 . Briefly, Illumina paired reads were aligned to the reference L.major Friedlin reference genome sequence obtained from TriTrypDB 73 using the Burrows-Wheeler Aligner (version 0.7.17) 74 , file formats transformed using samtools (version 1.10), and variant calling was done with VarScan2 (version 2.4.3) 75 to generate VCF files.…”

“…The occurrence of interspecies and intraspecies natural Leishmania hybrids has been recently demonstrated along with well documented experimentally derived hybrids exhibiting genome wide recombination events (Akopyants et al, 2009;Inbar et al, 2019;Cotton et al, 2020;Lypaczewski and Matlashewski, 2021). This phenomenon can lead to the emergence of novel Leishmania genotypes that may cause more than one clinical outcome, apart from contributing to the parasite genome diversity.…”

“…More recently, genomic and phylogenic analysis of L. donovani clinical isolates from Sri Lanka identified interspecies genome hybridization and recombination between L. donovani and Leishmania major/L. tropica revealing multiple mechanisms contribute to the atypical CL phenotype of L. donovani (Lypaczewski and Matlashewski, 2021).…”

“…Ένα πολύ σημαντικό χαρακτηριστικό που παρατηρείται επίσης στη φύση, είναι όταν δύο είδη Leishmania είναι συμπάτρια σε μία περιοχή να μην αποκλείεται ο υβριδισμός μεταξύ τους, αφού μπορούν να προσβάλλουν ταυτόχρονα τον ίδιο οργανισμό. Υβριδισμός έχει παρατηρηθεί μεταξύ των L. donovani και L. tropica στη Σρι Λάνκα (Lypaczewski et al, 2020), μεταξύ των L.…”

“…Η δημιουργία υβριδίου L. infantum και L. major παρατηρήθηκε και από τους Romano et al (2014) και έλαβε χώρα μέσα στη φλεβοτόμο σε πειραματικές συνθήκες. Ο υβριδισμός μεταξύ διαφορετικών ειδών Leishmania μπορεί να οδηγήσει σε αλλαγές στην παθολογία της ασθένειας που προκαλούν (Lypaczewski et al, 2020), δυσχεραίνοντας το έργο των ιατρών. Το αποτέλεσμα του υβριδισμού μπορεί να είναι ακόμη και η απόκτηση αντοχής στα φάρμακα (Romano et al, 2014).…”
